Tiny AVR Serial Port Programmer

摘要

Now you can program AVR microcontrollers via your PC's serial port for less than $10. Bruce's general-purpose, ATtiny15L-based AVR programmer plugs into a laptop's serial port and draws its power from the port's modem control lines. Atmel makes a series of wonderful, inexpensive, general-purpose eight-pin microcontrollers that go by the name of ATtiny. One part in particular, the ATtinyl5L microcontroller, has become one of my favorites because of its rich set of features and the design flexibility it offers. (No, I don't work for Atmel!) Atmel offers a wide variety of inexpensive flash-memory-based microcontrollers that all share the same AVR instruction set, which Atmel describes as RISC-based and optimized for high-level languages such as C.
